Patients with human immunodeficiency virus (HIV) have an increased risk of inoculation with nontyphoid Salmonella compared to the general population. While nontyphoid Salmonella commonly manifests as gastroenteritis, Salmonella bacteremia can be seen in patients with HIV. We present a case of disseminated Salmonellosis in a patient with HIV complicated by bronchopleural fistula and secondary empyema. Case Presentation. A 40-year-old African American male with HIV noncompliant with HAART therapy presented with complaints of generalized weakness, weight loss, cough, night sweats, and nonbloody, watery diarrhea of four weeks’ duration. A computed tomography (CT) scan demonstrated a bilobed large, thick-walled cavitary lesion in the right upper lobe communicating with the pleural space to form a bronchopleural fistula. Thoracentesis yielded growth of nontyphi Salmonella species consistent with empyema; he was treated with intravenous Ceftriaxone and underwent placement of chest tube for drainage of empyema with instillation of alteplase/dornase twice daily for three days. Repeat CT chest showed a hydropneumothorax. The patient subsequently underwent video-assisted thoracoscopy with decortication. The patient continued to improve and follow-up CT chest demonstrated improved loculated right pneumothorax with resolution of the right bronchopleural fistula and resolution of the cavitary lesions. Discussion. We describe one of the few cases of development of bronchopulmonary fistula and the formation of empyema in the setting of disseminated Salmonella. Empyema complicated by bronchopulmonary fistula likely led to failure of intrapleural fibrinolytic therapy and the patient ultimately required decortication in addition to antibiotics. While Salmonella bacteremia can be seen in immunocompromised patients, extraintestinal manifestations of Salmonella infection such as empyema and bronchopleural fistulas are uncommon. Bronchopleural fistulas most commonly occur as a postoperative complication of pulmonary resection. Conclusions. This case highlights the unusual pulmonary manifestations that can occur due to disseminated Salmonella in an immunocompromised patient as well as complex management decisions related to these complications.

Abstract Background Among persons living with human immunodeficiency virus (PHIV), incident heart failure (HF) rates are increased and outcomes are worse; however, the role of amino-terminal pro-B-type natriuretic peptide (NT-proBNP) concentrations among PHIV with HF has not been characterized. Methods Patients were derived from a registry of those hospitalized with HF at an academic center in a calender year. We compared the NT-proBNP concentrations and the changes in NT-proBNP levels between PHIV with HF and uninfected controls with HF. Results Among 2578 patients with HF, there were 434 PHIV; 90% were prescribed antiretroviral therapy and 62% were virally suppressed. As compared to controls, PHIV had higher admission (3822 [IQR, 2413–7784] pg/ml vs 5546 [IQR, 3257–8792] pg/ml, respectively; P < .001), higher discharge (1922 [IQR, 1045–4652] pg/ml vs 3372 [IQR, 1553–5452] pg/ml, respectively; P < .001), and lower admission-to-discharge changes in NT-proBNP levels (32 vs 48%, respectively; P = .007). Similar findings were noted after stratifying based on left ventricular ejection fraction (LVEF). In a multivariate analysis, cocaine use, a lower LVEF, a higher NYHA class, a higher viral load (VL), and a lower CD4 count were associated with higher NT-proBNP concentrations. In follow-up, among PHIV, a higher admission NT-proBNP concentration was associated with increased cardiovascular mortality (first tertile, 11.5; second tertile, 20; third tertile, 44%; P < .001). Among PHIV, each doubling of NT-proBNP was associated with a 19% increased risk of death. However, among patients living without HIV, each doubling was associated with a 27% increased risk; this difference was attenuated among PHIV with lower VLs and higher CD4 counts. Conclusions PHIV with HF had higher admission and discharge NT-proBNP levels, and less change in NT-proBNP concentrations. Among PHIV, VLs and CD4 counts were associated with NT-proBNP concentrations; in follow-up, higher NT-proBNP levels among PHIV were associated with cardiovascular mortality.

Abstract Abstract 4156 Introduction: Human Immunodeficiency Virus (HIV) and hepatitis C virus (HCV) infections are both associated with an increased risk of B-cell non-Hodgkin lymphoma (B-NHL). They are known to be preferentially diffuse large B-cell lymphoma (DLBCL), and Burkitt lymphoma subtypes in HIV infection, while marginal zone lymphoma (MZL) and DLBCL represent the main subtypes in HCV infected patients. The absence of increased risk of B-NHL in HIV-HCV co-infected patients compared to HIV infected patients was reported in epidemiological studies, but the clinico-pathological characteristics of B-NHL in the setting of such co-infection particularly in the era of HAART remains unclear. Patients and methods: We present the data of adult patients with B-NHL and HIV-HCV co-infection from the French ANRS CO16 Lymphovir cohort. This multicentric prospective cohort includes HIV infected patients with lymphoma. Each patient is followed every 6 months during 5 years. At each follow-up, a blood sample is withdrawn allowing ancillary studies. Data collection concerns clinical presentation, treatment and evolution of B-NHL and HIV and HCV infections. Pathological and cytological materials are centralized in order to allow their review and a concerted analysis by a group of expert hematopathologists (MR, SP, DC), haematologists and immunologists. Results: Among the 49 patients with B-NHL included in the cohort, 6 were HIV-HCV coinfected, [5 men and 1 woman, median age 47 years (range 36–67)]. They were included between october 2007 and august 2009 in 6 French centres. Transmission risk was intravenous drug abuse (n=4) and heterosexual transmission (n=2). Median duration from HIV diagnosis to B-NHL was 11 years (range 1–20), and the median nadir CD4 T-cell count was 194/mm3 (range 151–746) (nadir not available for 2 patients). Only one patient had developed AIDS before the diagnosis of NHL. HCV genotypic distribution was: genotype 1 (n=3), 2 (n=1), 4 (n=1), and not available (n=1). Median HCV viral load was 6.0 log (range 5.4–7.1). One patient had compensated cirrhosis and none of the patients were tested for cryoglobulinemia. Immunological assays showed the presence of monoclonal IgM Kappa in 1 patient and no positive rheumatoid factor. At the diagnosis of B-NHL, 4 patients received HAART and had an undetectable HIV load. In contrast, none of the patients were treated for HCV infection. The median interval between B-NHL diagnosis and last follow-up is 17 months (range 0.1–32 months). The histological subtype distribution is 4 MZL -including 2 extranodal MZL of MALT, 1 splenic lymphoma with villous lymphocytes (SLVL) and 1 lymphoplasmacytic lymphoma- and 2 EBV-negative DLBCL. All patients have extranodal involvement, including digestive tract (n=3), liver (n=2), bone marrow (n=2) and spleen (n=1). Median CD4 T-cell count at B-NHL diagnosis was 582/mm3 (range 235–1322) in MZL patients and 274/mm3 (200 and 347) in DLBCL patients. Following diagnosis, all patients were treated with HAART, associated with peg-interferon plus ribavirin in 1 patient. The 2 patients with DLBCL received R-CHOP, associated with methotrexate in 1 case. One patient with a partial response exhibited a neuromeningeal relapse and was treated with COPADM and CYVE regimen, allowing a complete and sustained response. The other patient died of serious infection after 2 courses of chemotherapy. Among patients with MZL, one patient received R-CVP and one received chlorambucil, allowing a complete response in both patients. The patient with SLVL received HAART then peg-interferon plus ribavirin, allowing normalization of lymphocytes count (5.89 at baseline vs. 1.69 × 109/L at 12 weeks of anti-HCV therapy) with a correlation between HCV virological and hematological response. Patient with lymphoplasmacytic lymphoma died of cardiac ischemia before the initiation of chemotherapy. Conclusions: This study describes the resurgence of MZL in HIV-HCV co-infected patients with restored immunity under HAART. Such B-NHL, very rarely described in HIV patients, occurs mainly in patients with control of HIV without history of AIDS but with active HCV infection. Histological subtypes and localizations resemble more to that observed in HCV infected patients than in HIV infected patients. These findings suggest the role of chronic antigenic stimulation by HCV and/or HIV and question about the interest of HCV antiviral therapy on NHL in co-infected patients. Disclosures: No relevant conflicts of interest to declare.

ABSTRACT Human astrocytes can be infected with human immunodeficiency virus type 1 (HIV-1) in vitro and in vivo, but, in contrast to T lymphocytes and macrophages, virus expression is inefficient. To investigate the HIV-1 life cycle in human fetal astrocytes, we infected cells with HIV-1 pseudotyped with envelope glycoproteins of either amphotropic murine leukemia virus or vesicular stomatitis virus. Infection by both pseudotypes was productive and long lasting and reached a peak of 68% infected cells and 1.7 μg of viral p24 per ml of culture supernatant 7 days after virus inoculation and then continued with gradually declining levels of virus expression through 7 weeks of follow-up. This contrasted with less than 0.1% HIV-1 antigen-positive cells and 400 pg of extracellular p24 per ml at the peak of astrocyte infection with native HIV-1. Cell viability and growth kinetics were similar in infected and control cells. Northern blot analysis revealed the presence of major HIV-1 RNA species of 9, 4, and 2 kb in astrocytes exposed to pseudotyped (but not wild-type) HIV-1 at 2, 14, and 28 days after infection. Consistent with productive infection, the 9- and 4-kb viral transcripts in astrocytes infected by pseudotyped HIV-1 were as abundant as the 2-kb mRNA during 4 weeks of follow-up, and both structural and regulatory viral proteins were detected in infected cells by immunoblotting or cell staining. The progeny virus released by these cells was infectious. These results indicate that the major barrier to HIV-1 infection of primary astrocytes is at virus entry and that astrocytes have no intrinsic intracellular restriction to efficient HIV-1 replication.

Hepatic Cytolysis

ABSTRACT In a cohort of 1,047 human immunodeficiency virus type 1-infected patients started on protease inhibitors (PIs), the incidence of severe hepatic cytolysis (alanine aminotransferase concentration five times or more above the upper limit of the normal level ≥ 5N) was 5% patient-years after a mean follow-up of 5 months. Only positivity for hepatitis C virus antibodies (hazard ratio [HR], 7.95;P < 10−3) or hepatitis B virus surface antigen (HR, 6.67; P < 10−3) was associated with severe cytolysis. Before starting patients on PIs, assessment of liver enzyme levels and viral coinfections is necessary.

Background:Nausea and vomiting are common during the first half of pregnancy and usually require only supportive measures. When symptoms are progressive and weight loss occurs, treatable causes should be sought by means of upper gastrointestinal endoscopy. We report a case of an immunocompetent gravida with invasiveCandida albicansesophagitis.Case:The immunocompetent primigravida developed progressive nausea, vomiting, epigastric pain, and a 4.1 kg weight loss during the second trimester of pregnancy. Treatment with metoclopramide and cimetidine for presumed gastroesophageal reflux was not effective. The patient had normal T-cell CD4 and CD8 subsets and was human immunodeficiency virus (HIV) antibody negative. Upper gastrointestinal endoscopy revealedC. albicansesophagitis which was treated with oral nystatin. The esophagitis had resolved completely when reassessed postpartum. The use of histamine2blockers is associated with an increased risk for fungal esophagitis and may have been a contributing cause in this case.Conclusion:Pregnant patients with persistent nausea, vomiting, and weight loss should be evaluated by endoscopy for fungal esophagitis.

Immunodeficiency Syndrome

Thrombocytopenia has emerged as a major hematological manifestation associated with AIDS (acquired immunodeficiency syndrome) and human immunodeficiency virus (HIV)-positive patients. A study of homosexual patients with thrombocytopenia indicates 93 percent had serological evidence of HIV exposure whereas only 33 percent of homosexuals without thrombocytopenia exhibited this finding. Thrombocytopenia in patients with hemophilia has been identified as an increased risk factor for AIDS development and has been observed in about one-third of children with AIDS. The management of thrombocytopenia in HIV-infected patients poses a therapeutic dilemma for clinicians since many of the traditional modalities for treating immune thrombocytopenia may adversely affect the underlying disease process or further compromise the immune system. Splenectomy, corticosteroids, danazol, intravenous immune globulin, vincristine, and RHo(D) immune globulin have all been used with variable results. A new technique that physically removes antibodies and immune complexes associated with thrombocytopenia is under investigation. Due to either toxicity or the high incidence of transient response, asymptomatic patients may not be candidates for treatment.

There are many reasons for patients infected with human immunodeficiency virus (HIV) to develop cerebrovascular disease. The HIV virus itself however may be a cause of vessel wall pathology. We present a clinical and pathological study of a patient who was HIV positive and presented with a subarachnoid haemorrhage. Cerebral angiography and later histology confirm that there was extensive vessel wall injury with dissection and a false aneurysm of the right middle cerebral artery.
